HEEL-BURNISH SPECIFICATION forming part of Letters Application filed October 3, 1889.

. T0 all whom it may concern.-

Be it known that I, LEW K. S'IRANG, of Haverhill, in the county of Essex, State of Massachusetts, have. invented certain new and useful Improvements in Heel-Burnishin g Machines, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a sectional elevation showing my improvement in use; Fig. 2, elevations showing details of construction; Fig. 3, an end elevation of the burnishing-roll and handle.

Like letters and figures of reference indicate corresponding parts in the different figures of the drawings.

My invention relates to a device for burnishing or finishing the heels of boots or shoes; and it consists in certain novel features hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, and more efiective device of this character than is now in ordinary use.

The nature and operation of the improve,- ment will be readily understood by all conversant with such matters from'the following explanation In the drawings, A represents a forked standard, in the arms of which a shaft 1) is journaled, said shaft bearing a fast pulley (Z and loose pulley f. A wooden handle B has aforked metallic tip 9 secured thereto, in the arms of which a shaft h is journaled, screwthreaded on one end at i. A chain. j is secured in the opposite end of the handle, whereby it may be suspended in any convenient position. A burnishing-wheel D is secured on the shaft it between the arms of the tip g. Said wheel has a working face 7t, curved or oval in crosssection, and of a shape to register with the curve of a heel 15 on the shoe C. The face it is corrugated laterally, enabling it to take better 011 the surface of the heel and polish it much more of lNG MACHINE.

fectively than will a smooth surface. A coupling H has a threaded socket Zin one end to receive the threaded end of the wheelshaft h. The opposite end is provided with an annular chamber m, the inner end of which is enlarged at 1). Longitudinal slots or grooves q (see Fig. 2) are formed in the walls of the chamber and extend into the enlarged portion. A flexible rod K, (see Fig. 2,) preferably composed of hard rubber, has two studs r formed on opposite sides of each end thereof and adapted to enter the grooves q and chamber 19 of the coupling. Similar studs t are formed on the rod at opposite sides thereof, also adapted to enter said grooves and prevent the rod from rotating in the coupling, the studs 7", being inserted in the enlarged portion 29 of the chamber m and turned until they do not register with the grooves, preventing said rod from being withdrawn from said coupling. A section of metallic rod 1) is provided'at each end with one of the couplings H, into one of which the opposite end of the flexible rod K is secured. A similar flexible rod K connects the opposite end of the rod 1) with a coupling 11 011 one end of the shaft 1) in the standard A. These shafts and the elastic rods K form a flexible driving-shaft P for the burnishingwheel.

In the use of my improvement the wheel D is heated by suspending it in alamp-flame in the ordinary manner of heating burnishingirons. Power being applied to the pulley v d from any convenient source, the shaft P is rotated, rapidly revolving the wheel D. The operator, grasping the wooden handle B, is enabled to hold said wheel firmly in engagement with the edge of the heel 15, which is thereby polished in the usual manner. The flexible portions K. of the shaft 1? permit the operator to adjust the wheel at any desired 0 angle and the device to be moved laterally for heating the wheel or other purposes in a manner which. will be readily understood without a more explicit description.

The rubber sections K of the shaft can eas ily be removed. and replaced when worn by Withdrawing their studs i from the couplingpulley d, the rod 1;, the chambered couplings 1o grooves and revolving said sections until their H, secured to said shafts and rod, and the studs 7' register with said grooves. flexible rods K, detach-ably disposed in said Having thus explained inyinvention, what couplings, all being arranged to operate sub- 5 I claim isstantially as described.
